Jokes aside, upon reading your article, some rather obvious red flags stuck out to me. First and foremost, the idea that you don't do sparring and claim that this prepares you for self defense is laughable, and so is the reasoning behind it. Think about this from a logical standpoint; If you've NEVER actually done something, how do you know you can do it?
For example, groin kicks. You do know that some people aren't phased by kicks to the groin right? So what if your entire attack strategy revolves around kicking someone in the nuts (like that hilarious video I posted above) and it doesn't work?
In BJJ we practice choking, and we choke someone until they submit. If they don't submit, they pass out. However, there are some people who you simply aren't able to choke in certain positions, which is why it's invaluable for us to roll full blast to see what works and what doesn't work. If my entire strategy revolved around the triangle choke for example, and I never trained to deal with someone who simply can't be choked out with that choke, I'm royally screwed. However, since I have dealt with people like that, I know that I can immediately move out of the choke and go for arm bars, sweeps, or shoulder locks instead.
This is also why we've removed the "deadly" techniques from practice; so that we can practice the "safe" techniques over and over again against fully resistant partners until we master them. Learning the technique isn't enough, you have to know how to APPLY the technique as well.
Back to the triangle choke for example #2; I learned the triangle choke fairly early in my training. I knew it was effective, and I knew how to do it, however I simply could never get it to work for ME. It took years to develop an effective triangle choke, and frankly I would have never known I needed to work on it if it wasn't for sparring/rolling. Yeah, I would slap the legs together right, yeah I would grab the back of their head and push down, but I simply wasn't choking them. So I decided to spend 6 months just training the triangle until I got it right. Every roll I started from guard just so that I could practice that one technique because I knew it was important for self defense. Eventually I got it, and I had one of the best triangle chokes in my gym.
About a year later I got into a self defense situation where the triangle choke saved my life. If I had never sparred and just thought I "knew" the technique, I'd probably be pushing up daises right now.
I also can't stress just how terrible the concept of feint striking is. I'm not sure I read this correctly, but are you saying that you guys are purposely pulling punches? Are you actually getting hit at this school? I can unequivocally tell you right now that if you're training for self defense, you need to know how to take a full on strike, and you need to know HOW to strike. And the only way you learn that is by hitting a moving target trying to knock your block off.
Finally, the combat sports comment is just silly. Yeah we fight with "rules", but that doesn't mean that what we're doing still won't kill or maim you. If I hold my choke for a few minutes after you've passed out, you're dead. If I get some clown in a kimura and keep moving my body in the same direction, their shoulder is going to pop. If get them in a heel hook, they're not walking for a long time. This nonsense about "rules" is just silly talk, because people in combat sports know how to actually do the deed. They do it constantly, over and over again, against trained, resisting partners.
Boxers probably have more rules than any other combat sport/MA out there. I'd tell someone to train there before I'd recommend any Krav Maga school.
In the end, I'm happy you've found a martial art you enjoy. Unfortunately, I'm afraid you've drunk a little too much of their Kool-Aid. Cross-train in some other styles and see if your viewpoint changes. If not, good luck.
